2. An example of a system with one outdoor unit to which 2 or more LOSSNAY units are connected
(manual address setup for both indoor and outdoor units)
(1) Sample control wiring
(2) Cautions
1) ME remote controller and MA remote controller cannot
both be connected to the same group of indoor units.
2) No more than 2 MA remote controllers can be connected
to a group of indoor units.
3) When the number of the connected indoor units is as
shown in the table below, one or more transmission
boosters (sold separately) are required.
To connect two transmission boosters, connect them in
parallel. (Observe the maximum number of connectable
indoor units that are listed in the specifications for each
outdoor unit.)
When the 200 and 250 models are not in-
cluded in the connected indoor units
When the 200 and 250 models are includ-
ed in the connected indoor units

The table above shows the number of transmission
boosters that is required by the system with three BC
controllers. For each BC controller that is subtracted
from the above-mentioned system, two additional indoor
units can be connected.
(3) Maximum allowable length
